We are putting footnotes in our book document, but found that as soon as a footnote reaches the number 10, it adds this space between the footnote number and the footnote text. We have checked our Character Styles (none are applied, Paragraph Styles (they are the same as the ones applied to numbers 1-9), and tried to adjust our tabs and indents, but nothing has fixed it yet.

We are desperate for help. If you have any suggestions, please let us know.

the footnote settings contain the Tab symbol between the number and the text. Yours is quite small, so when the number achieves 10 (2 digits), it becomes longer than the tab space. You have to change the Tab option in the Paragraph style which you use for your footnotes.
